Project Scope

Our senior backend developers joined the client’s frontend developers and worked together for 6 months. The first task was to improve and optimize the ecommerce website. We helped the client fix all website issues, improve performance, and prevent crashes during peak sales periods.

Our next task was to make the website more user-friendly. Forbytes’ dedicated team built multiple tools and integrated them with Lekmer.se, including a rating and review system, a search engine recommendation tool, a Wishlist feature, and a few others.

Also, Lekmer’s marketing team needed the functionality that would ease their work and facilitate the creation of marketing campaigns. Our senior developers designed, built, and delivered several custom features to meet all these needs.

Among others, we built the feature allowing managers to create special offers and sell products in the so-called product packages. This function grew the client’s sales as users began to order packages of products instead of ordering single items.
